特許第５２３５７８９号公報Japanese Patent No. 5235789
　特許文献１の技術では、部材が棒状部材や支持ブロックなので分解状態で梱包すると、コンパクト化でき、持ち運びや収納に便利である。また組み立てが容易であると共に、使用目的に合わせて幅や高さなどの大きさを容易に変更することができる。しかし、さらにより一層、効果的に用いるための改善点があった。
　例えば、棚部を形成する棒状部材の端部に形成された被係合部が、支持用切欠き部に設けた係合部に係合する構成であるが、棒状部材の端部の側面に上下方向に刻設された溝部であるので、強度的に弱くなってしまう。 In the technique of Patent Document 1, since the member is a rod-like member or a support block, if it is packed in a disassembled state, it can be made compact and convenient for carrying and storage. In addition, the assembly is easy, and the size such as the width and the height can be easily changed according to the purpose of use. However, there were improvements for even more effective use.
For example, the engaged portion formed at the end portion of the rod-shaped member that forms the shelf portion is configured to engage with the engaging portion provided in the support notch portion, but on the side surface of the end portion of the rod-shaped member. Since the grooves are engraved in the vertical direction, the strength is weakened.
　さらに、複数の支持ブロックを上下に連結するとき、各支柱部の下部または上部に爪部が設けられており、前記各爪部が各支柱の上部または下部に設けた爪受け溝に係合する構造である。しかし、各爪部と各爪受け溝は、支持ブロックを上下に連結する時に引っ掛かるが、分解する時に外しやすくするには、引っ掛け代（係合代）を小さくする必要がある。そのため、各爪部と各爪受け溝の位置関係は微妙な調整を要する。また、使用頻度が多くなると、各爪部と各爪受け溝が摩耗するために連結度合いを強くすることが難しくなる。また、組み立てた支持ブロックを分解する際に、係合している各爪部と各爪受け溝を解除するのがそれほど簡単ではない。 Further, when the plurality of support blocks are connected vertically, a claw portion is provided at the lower portion or the upper portion of each column portion, and each of the claw portions engages with a claw receiving groove provided at the upper portion or the lower portion of each column. Structure. However, each claw portion and each claw receiving groove are hooked when the support block is connected vertically, but it is necessary to reduce a hook allowance (engagement allowance) in order to easily remove the support block when disassembling. Therefore, the positional relationship between each claw portion and each claw receiving groove requires delicate adjustment. In addition, when the frequency of use increases, it becomes difficult to increase the degree of connection because each claw portion and each claw receiving groove wear. Further, when disassembling the assembled support block, it is not so easy to release the engaged claw portions and the claw receiving grooves.
　本発明は上記に鑑みなされたものであり、組み立てたブロック構造の強度を向上し、組み立てたブロック構造を分解することが容易である組立式ブロック構造およびロック解除具を提供することを課題とする。 The present invention has been made in view of the above, and it is an object of the present invention to provide an assembled block structure and an unlocking tool that improve the strength of the assembled block structure and can easily disassemble the assembled block structure. .

For example, in the case of the support block 20 of the present embodiment, among the six support portions 21 provided along the longitudinal direction, the cross-sectional shape is positioned at one end. The supporting column portion 21a is formed in a substantially rectangular cross section, and the supporting column portion 21b located at the other end is formed in a substantially semi-elliptical cross section. However, in order to improve the strength, it is preferable that the side surface 21c constituting each support column 21 is formed as close to the lower end edge as possible.
　隔壁部２２は、支持ブロック２０の高さ方向の略中央付近であって、長手方向に沿って隣接する支柱部２１，２１間に跨るように設けられている。その結果、隣接する支柱部２１，２１間において、隔壁部２２を挟んだ上下に２つの切欠き部（支持用切欠き部２３、受入用切欠き部２６）が形成される。 The partition wall portion 22 is provided in the vicinity of the substantially central portion in the height direction of the support block 20 and straddling between the column portions 21 and 21 adjacent to each other along the longitudinal direction. As a result, two notch portions (a support notch portion 23 and a receiving notch portion 26) are formed on the upper and lower sides of the partition wall portion 22 between the adjacent support column portions 21 and 21.
　支持用切欠き部２３は、隔壁部２２の上部に形成された上面開口の切欠きであり、後述の棒状部材４０の端部４１が収まる大きさで形成されている。支持用切欠き部２３の内側面は、後述の棒状部材４０の端部４１に形成された被係合部に係合する係合部が形成されている。詳しくは後述するが、前記被係合部は、棒状部材４０の端部４１に設けたホゾ部４２である。前記係合部は、前記ホゾ部４２を挿入可能に形成したアリ溝２４である。 The support cutout portion 23 is a cutout in the upper surface opening formed in the upper portion of the partition wall portion 22 and is formed to have a size that can accommodate an end portion 41 of a rod-like member 40 described later. An engaging portion that engages with an engaged portion formed at an end portion 41 of a rod-like member 40 described later is formed on the inner side surface of the support cutout portion 23. As will be described in detail later, the engaged portion is a relief portion 42 provided at the end portion 41 of the rod-shaped member 40. The engaging portion is a dovetail groove 24 in which the ridge portion 42 can be inserted.
　また、本実施形態では、各支柱部２１の厚み方向の中間部同士を連結する連結壁２５が設けられており、支持用切欠き部２３は、前記連結壁２５を挟んだ両側に形成されている。したがって、本実施形態では、各支持用切欠き部２３に棒状部材４０の端部４１が挿入される挿入長さは、支柱部２１の厚みから連結壁２５の厚みを差し引いたものの略半分に相当する長さとなる。 Moreover, in this embodiment, the connection wall 25 which connects the intermediate parts of the thickness direction of each support | pillar part 21 is provided, and the notch part 23 for support is formed in the both sides on both sides of the said connection wall 25. Yes. Therefore, in this embodiment, the insertion length in which the end portion 41 of the rod-like member 40 is inserted into each support cutout portion 23 corresponds to substantially half of the thickness of the support column portion 21 minus the thickness of the connecting wall 25. It becomes the length to do.
　受入用切欠き部２６は、隔壁部２２の下部に形成された下面開口の切欠きであり、正面から見て、後述の棒状部材４０の端部４１を挿入可能な面積で形成されている。 The receiving cutout portion 26 is a cutout in the lower surface opening formed in the lower portion of the partition wall portion 22 and has an area where an end portion 41 of a rod-like member 40 described later can be inserted when viewed from the front.
　支持フレーム１３は、複数個の支持ブロック２０を上下に連接して形成する。そのため、支持ブロック２０の各支柱部２１における上部及び下部は、上下に配置される他の支持ブロック２０の各支柱部２１の下部及び上部とそれぞれ嵌合可能に形成されている。つまり、支柱部２１の上部の外径を下部の内径よりも小さくしている。したがって、上下に支持ブロック２０を連接すると、下側に配置される支持ブロック２０の上部が、上側に配置される支持ブロック２０の下部の周壁内に嵌ることになる。 The support frame 13 is formed by connecting a plurality of support blocks 20 vertically. Therefore, the upper part and the lower part in each support | pillar part 21 of the support block 20 are formed so that a lower part and an upper part of each support | pillar part 21 of the other support block 20 arrange | positioned up and down can each be fitted. That is, the outer diameter of the upper part of the column part 21 is made smaller than the inner diameter of the lower part. Therefore, if the support block 20 is connected up and down, the upper part of the support block 20 arrange | positioned below will fit in the surrounding wall of the lower part of the support block 20 arrange | positioned above.
　上側に配置される支持ブロック２０の倒れを抑制するために、支柱部２１のいずれか少なくとも一つに、本実施形態では、長手方向の一端に位置する支柱部２１ａに、上方に延長するように形成したボス部２７ａが、上側に配置された支持ブロック２０の支柱部２１ａの周壁内のボス用穴部３３ａに挿入される。さらに、長手方向の他端に位置する支柱部２１ｂに、上方に延長するように形成したボス部２７ｂが、上側に配置された支持ブロック２０の支柱部２１ｂの周壁内のボス用穴部３３ｂに挿入される。なお、支持フレーム１３の上端に配置される支持ブロック２０のうち、最も上部に配設されるもの（図１に示した符号２０Ａの支持ブロック）は、美観上、例えば、図１に示すように、ボス部２７ａ，２７ｂを形成しないものを用いることが好ましい。 In order to suppress the falling of the support block 20 arranged on the upper side, in this embodiment, at least one of the support columns 21 is extended upward to the support column 21a located at one end in the longitudinal direction. The formed boss portion 27a is inserted into the boss hole portion 33a in the peripheral wall of the support column portion 21a of the support block 20 disposed on the upper side. Further, a boss portion 27b formed so as to extend upward in the support column 21b located at the other end in the longitudinal direction is formed in the boss hole 33b in the peripheral wall of the support column 21b of the support block 20 arranged on the upper side. Inserted. Of the support blocks 20 arranged at the upper end of the support frame 13, the one arranged at the top (the support block of reference numeral 20A shown in FIG. 1) is aesthetically pleasing, for example, as shown in FIG. It is preferable to use one that does not form the boss portions 27a and 27b.
　ここで、ボス部２７ａ，２７ｂを備えた支持ブロック２０と、ボス部２７ａ，２７ｂを備えていない最上部に配設される支持ブロック２０Ａの外観構成の違いを明確にするため、図１２（ａ）～（ｉ）に前者の支持ブロック２０の全体構成を、図１３（ａ）～（ｈ）に後者の支持ブロック２０Ａの全体構成を参考として具体的に示している。 Here, in order to clarify the difference in appearance configuration between the support block 20 provided with the boss portions 27a and 27b and the support block 20A provided at the uppermost portion not provided with the boss portions 27a and 27b, FIG. ) To (i) specifically show the entire configuration of the former support block 20, and FIGS. 13A to 13H specifically show the overall configuration of the latter support block 20A.
　ボス部２７ａは中空の断面略四角形に形成され、周壁面には、爪部２８ａ，２８ｂを設けている。本実施形態では、爪部２８ａ，２８ｂが、ボス部２７ａの正面側と背面側にほぼ対向する位置に配置している。 The boss portion 27a is formed in a substantially square shape with a hollow cross section, and claw portions 28a and 28b are provided on the peripheral wall surface. In the present embodiment, the claw portions 28a and 28b are disposed at positions substantially opposite to the front side and the back side of the boss portion 27a.
　図３及び図４に示すように周壁の一部に逆Ｕ字形の切欠きを形成し、逆Ｕ字形の切欠きの内側片が弾力性を有する爪部用バネ片２９ａ，２９ｂとなる。爪部用バネ片２９ａ，２９ｂは、下部がボス部２７ａの周壁と一体であり、上部が内側や外側へ撓むバネ性を有することになる。爪部用バネ片２９ａ，２９ｂの上端部の外側には前記爪部２８ａ，２８ｂを備える。したがって、前記爪部２８ａ，２８ｂを内側へ向けて押圧すると、爪部用バネ片２９ａ，２９ｂによって、爪部２８ａ，２８ｂを外側へ付勢する付勢力が発生することになる。 3 and 4, an inverted U-shaped notch is formed in a part of the peripheral wall, and the inner pieces of the inverted U-shaped notch become elastic nail spring pieces 29a and 29b. The claw part spring pieces 29a and 29b have a spring property that the lower part is integral with the peripheral wall of the boss part 27a and the upper part is bent inward or outward. The claw portions 28a and 28b are provided outside the upper ends of the claw portion spring pieces 29a and 29b. Therefore, when the claw portions 28a and 28b are pressed inward, the urging force for urging the claw portions 28a and 28b outward is generated by the claw portion spring pieces 29a and 29b.
　本実施形態では、爪部２８ａ，２８ｂは、ボス部２７ａの周壁面から外側へ突出しており、ボス部２７ａをボス用穴部３３ａに挿入する方向に対し、その反対である下方に向けて徐々に突出する方向に裾広がりに傾斜するように、該爪部２８ａ，２８ｂの外面に傾斜部３１ａ，３１ｂが形成されている。 In the present embodiment, the claw portions 28a, 28b protrude outward from the peripheral wall surface of the boss portion 27a, and gradually move downward in the opposite direction to the direction in which the boss portion 27a is inserted into the boss hole portion 33a. Inclined portions 31a and 31b are formed on the outer surfaces of the claw portions 28a and 28b so as to incline toward the bottom in the projecting direction.
　一方、上側に配置された支持ブロック２０の支柱部２１ａの周壁内のボス用穴部３３ａは、前記爪部２８ａ，２８ｂと係合する爪受部３５ａ，３５ｂを備えたロック用孔部３４ａ，３４ｂを設けている。つまり、ロック用孔部３４ａ，３４ｂの下半円の部分が爪受部３５ａ，３５ｂとなる。本実施形態では、前記ロック用孔部３４ａ，３４ｂが、ボス用穴部３３ａの正面側と背面側にほぼ対向する位置に配置している。 On the other hand, a boss hole 33a in the peripheral wall of the support column 20a of the support block 20 arranged on the upper side is a lock hole 34a provided with claw receiving portions 35a, 35b engaged with the claw portions 28a, 28b. 34b is provided. That is, the lower semicircle portions of the locking holes 34a and 34b become the claw receiving portions 35a and 35b. In the present embodiment, the locking holes 34a and 34b are arranged at positions substantially opposite to the front side and the back side of the boss hole 33a.
　したがって、上下に支持ブロック２０を連接するとき、下側の支持ブロック２０の支柱部２１ａ，２１ｂのボス部２７ａ，２７ｂが、上側の支持ブロック２０の支柱部２１ａ，２１ｂの対応するボス用穴部３３ａ，３３ｂに挿入される。支柱部２１ａ，２１ｂの構造は、ほぼ同様であるので、支柱部２１ａについて詳しく説明する。 Therefore, when connecting the support blocks 20 up and down, the boss portions 27a and 27b of the support column portions 21a and 21b of the lower support block 20 correspond to the corresponding boss hole portions of the support column portions 21a and 21b of the upper support block 20. 33a and 33b are inserted. Since the structures of the support columns 21a and 21b are substantially the same, the support column 21a will be described in detail.
　下側の支持ブロック２０のボス部２７ａの爪部２８ａ，２８ｂは、図４（ａ）に示すように、上側の支持ブロック２０のボス用穴部３３ａの内周の位置より外側へ突出している。挿入すると、図４（ｂ），（ｃ）に示すように、ボス用穴部３３ａの端縁が、ボス部２７ａの爪部２８ａ，２８ｂの傾斜部３１ａ，３１ｂを爪部用バネ片２９ａ，２９ｂの付勢力に抗して内側へ押圧する。さらに挿入すると、図４（ｄ）に示すように、爪部用バネ片２９ａ，２９ｂの外側への付勢力によって、ボス部２７ａの爪部２８ａ，２８ｂが対応するボス用穴部３３ａのロック用孔部３４ａ，３４ｂへ挿入して爪受部３５ａ，３５ｂに係合する。 As shown in FIG. 4A, the claw portions 28a and 28b of the boss portion 27a of the lower support block 20 protrude outward from the inner peripheral position of the boss hole portion 33a of the upper support block 20. . When inserted, as shown in FIGS. 4B and 4C, the end edge of the boss hole 33a causes the claw portions 31a and 31b of the claw portions 28a and 28b of the boss portion 27a to move to the claw portion spring pieces 29a, It pushes inward against the urging force of 29b. When inserted further, as shown in FIG. 4 (d), the claw portions 28a, 28b of the boss portion 27a are for locking the corresponding boss hole portion 33a by the outward biasing force of the claw portion spring pieces 29a, 29b. It is inserted into the holes 34a and 34b and engaged with the claw receiving portions 35a and 35b.
　なお、ボス部２７ｂは、前述のボス部２７ａと同様の構造であるので、詳しい説明は省略する。つまり、爪部２８ａ，２８ｂを備えた爪部用バネ片２９ａ，２９ｂを有する。また、上側に配置された支持ブロック２０の支柱部２１ｂの周壁内のボス用穴部３３ｂは、前述のボス用穴部３３ａと同様の構造であるので、詳しい説明は省略する。つまり、爪受部３５ａ，３５ｂを備えたロック用孔部３４ａ，３４ｂを有する。 Since the boss portion 27b has the same structure as the boss portion 27a described above, detailed description thereof is omitted. That is, it has claw part spring pieces 29a and 29b provided with claw parts 28a and 28b. Further, the boss hole 33b in the peripheral wall of the support column 21b of the support block 20 arranged on the upper side has the same structure as the boss hole 33a described above, and thus detailed description thereof is omitted. That is, it has the locking holes 34a and 34b provided with the claw receiving portions 35a and 35b.
　したがって、上下に支持ブロック２０を連接すると、ボス部２７ａの爪部２８ａ，２８ｂが対応するボス用穴部３３ａのロック用孔部３４ａ，３４ｂの爪受部３５ａ，３５ｂに係合する。また、ボス部２７ｂの爪部２８ａ，２８ｂも対応するボス用穴部３３ｂのロック用孔部３４ａ，３４ｂの爪受部３５ａ，３５ｂに係合する。その結果、上下の支持ブロック２０の連結度合いを一層、高めることができるので、支持ブロック２０の倒れ抑制機能が向上する。 Therefore, when the support block 20 is connected vertically, the claw portions 28a and 28b of the boss portion 27a engage with the claw receiving portions 35a and 35b of the lock hole portions 34a and 34b of the corresponding boss hole portion 33a. Further, the claw portions 28a and 28b of the boss portion 27b also engage with the claw receiving portions 35a and 35b of the locking hole portions 34a and 34b of the corresponding boss hole portion 33b. As a result, since the degree of connection between the upper and lower support blocks 20 can be further increased, the function of suppressing the falling of the support block 20 is improved.
　図１及び図３に示した態様では、支持フレーム１３の最下部の支持ブロック２０の長手方向の一端に位置する支柱部２１ａの周壁内のボス用穴部３３ａと、他端に位置する支柱部２１ｂの周壁内のボス用穴部３３ｂにキャスタ５０を取り付けている。前記キャスタ５０は、図５（ａ），（ｂ）に示すように、ボス用穴部３３ａ，３３ｂのいずれに対しても挿入可能な取付用ボス部５１を備えている。 1 and 3, the boss hole 33a in the peripheral wall of the support column 21a located at one end in the longitudinal direction of the lowermost support block 20 of the support frame 13, and the support column positioned at the other end The casters 50 are attached to the boss holes 33b in the peripheral wall 21b. As shown in FIGS. 5A and 5B, the caster 50 includes a mounting boss 51 that can be inserted into any of the boss holes 33a and 33b.
　最下部の支持ブロック２０において、図５（ａ）に示すように、支柱部２１ａの断面略方形状のボス用穴部３３ａには、隣り合う支柱部２１の側に位置する周壁面に、上下方向に長い２つのガイドレール部３６，３６を突出している。さらに、前記ボス用穴部３３ａには、２つのガイドレール部３６，３６の周壁面と対向する周壁面に、２つのガイドレール部３７，３７を突出している。一方、支柱部２１ｂの断面略半楕円状のボス用穴部３３ｂには、隣り合う支柱部２１の側に位置する周壁面に、前記ボス用穴部３３ａと同様の上下方向に長い２つのガイドレール部３６，３６を突出している。 In the lowermost support block 20, as shown in FIG. 5A, the boss hole 33 a having a substantially rectangular cross section of the support column 21 a has upper and lower sides on the peripheral wall surface located on the side of the adjacent support column 21. Two guide rail portions 36, 36 that are long in the direction protrude. Further, two guide rail portions 37, 37 protrude from the boss hole 33 a on the peripheral wall surface facing the peripheral wall surfaces of the two guide rail portions 36, 36. On the other hand, in the boss hole 33b having a substantially semi-elliptical cross section of the column 21b, two guides that are long in the vertical direction similar to the boss hole 33a are provided on the peripheral wall surface located on the adjacent column 21 side. The rail parts 36 and 36 protrude.
　キャスタ５０の取付用ボス部５１は、支柱部２１ｂの断面略半楕円状のボス用穴部３３ｂに挿入可能な断面略半楕円状に形成し、該断面略半楕円状の平面部に、前述の２つのガイドレール部３６，３６をガイドするための２つのガイド溝部５２，５２を形成している。さらに、略半楕円状の周面には、前述の２つのガイドレール部３７，３７をガイドするための２つのガイド溝部５３，５３を形成している。 The mounting boss portion 51 of the caster 50 is formed in a substantially semi-elliptical cross-section that can be inserted into the boss hole 33b having a semi-elliptical cross-section in the support column 21b. Two guide groove portions 52, 52 for guiding the two guide rail portions 36, 36 are formed. Further, two guide groove portions 53, 53 for guiding the above-described two guide rail portions 37, 37 are formed on the substantially semi-elliptical peripheral surface.
　なお、キャスタ５０の取付用ボス部５１は中空の断面略四角形からなり、周壁面には、前述のボス部２７ａ，２７ｂと同様に、爪部２８ａ，２８ｂを備えた爪部用バネ片２９ａ，２９ｂを設けている。 Note that the mounting boss 51 of the caster 50 has a substantially rectangular cross section, and the claw spring pieces 29a provided with the claw portions 28a and 28b on the peripheral wall surface, similar to the boss portions 27a and 27b described above. 29b is provided.
　本実施形態では、ボス部２７ａの爪部２８ａ，２８ｂと、ボス部２７ｂの爪部２８ａ，２８ｂと、取付用ボス部５１の爪部２８ａ，２８ｂとは、位置関係や大きさを同じ形状としている。また、支柱部２１ａの周壁内のボス用穴部３３ａの爪受部３５ａ，３５ｂと、支柱部２１ｂの周壁内のボス用穴部３３ｂの爪受部３５ａ，３５ｂとは、位置関係や大きさを同じ形状としている。したがって、キャスタ５０は、支柱部２１ａのボス用穴部３３ａと、支柱部２１ｂのボス用穴部３３ｂのいずれにも簡単に装着可能となる。その装着の仕方は、図４（ａ）～（ｄ）に示した支柱部２１ａと同様である。 In the present embodiment, the claw portions 28a and 28b of the boss portion 27a, the claw portions 28a and 28b of the boss portion 27b, and the claw portions 28a and 28b of the mounting boss portion 51 have the same positional relationship and size. Yes. Further, the claw receiving portions 35a and 35b of the boss hole portion 33a in the peripheral wall of the column portion 21a and the claw receiving portions 35a and 35b of the boss hole portion 33b in the peripheral wall of the column portion 21b are in a positional relationship and size. Have the same shape. Therefore, the caster 50 can be easily attached to both the boss hole 33a of the support column 21a and the boss hole 33b of the support column 21b. The mounting method is the same as that of the support column 21a shown in FIGS. 4 (a) to 4 (d).
　横フレーム１４は、複数本の棒状部材４０によって形成される。棒状部材４０は、図６に示したように、各端部４１，４１の側面に上下方向に設けたホゾ部４２，４２を形成している。このホゾ部４２は、前述の支持用切欠き部２３に設けた係合部であるアリ溝２４に係合する被係合部として機能する。アリ溝２４及びホゾ部４２は、単なる係合片や溝部に比べて、支持用切欠き部２３の係合部及び棒状部材４０の端部４１において強度的に強くなり、横フレームの強度を向上することができる。 The horizontal frame 14 is formed by a plurality of rod-shaped members 40. As shown in FIG. 6, the rod-shaped member 40 forms side portions 42, 42 provided on the side surfaces of the end portions 41, 41 in the vertical direction. The relief portion 42 functions as an engaged portion that engages with the dovetail groove 24 that is an engaging portion provided in the above-described support cutout portion 23. The dovetail groove 24 and the ridge portion 42 are stronger at the engagement portion of the support cutout portion 23 and the end portion 41 of the rod-like member 40 than the simple engagement piece or groove portion, and improve the strength of the horizontal frame. can do.
　また、各棒状部材４０の端部４１は、受入用切欠き部２６のそれぞれを正面から見た場合の面積よりも小さな断面積で形成されている。ただし、支持用切欠き部２３に係合する端部４１の断面積がこのような条件を備えていればよく、端部４１以外の部分の断面積（ないしは外径）はそれより大きくても構わない。 Further, the end portion 41 of each rod-shaped member 40 is formed with a cross-sectional area smaller than the area when each of the receiving cutout portions 26 is viewed from the front. However, the cross-sectional area of the end portion 41 that engages with the support cutout portion 23 only needs to satisfy such a condition, and the cross-sectional area (or outer diameter) of the portion other than the end portion 41 may be larger than that. I do not care.
　各棒状部材４０は、杉や桧等の間伐材から形成すると、間伐材の有効利用が図られるため好ましいが、棒状部材４０の材料が間伐材に限定されるものではない。他の木材（製材の端材等も含む）、合成樹脂、金属製のパイプ材等を用いることもできる。しかし、軽量化、資源の有効利用、コストの観点を総合すると、上記のように間伐材を用いることが好ましい。 Each rod-like member 40 is preferably formed from thinned timber, such as cedar and straw, because the thinned material can be effectively used, but the material of the rod-like member 40 is not limited to the thinned material. Other woods (including lumber ends), synthetic resins, metal pipes, and the like can also be used. However, when considering light weight, effective use of resources, and cost, it is preferable to use thinned wood as described above.
　本実施形態においては、支持ブロック２０を上下に連接していく。この際、上記のように下側に位置する支持ブロック２０のボス部２７ａ，２７ｂを、上側に位置する支持ブロック２０の両端の支柱部２１ａ，２１ｂのボス用穴部３３ａ，３３ｂに挿入する。すると、図４（ａ）～（ｄ）に示したように、支柱部２１ａにおいては、ボス部２７ａの爪部２８ａ，２８ｂが対応するボス用穴部３３ａのロック用孔部３４ａ，３４ｂへ挿入して爪受部３５ａ，３５ｂに係合して簡単にロックされる。支柱部２１ｂにおいても、支柱部２１ａと同様に簡単にロックされる。 In this embodiment, the support block 20 is connected up and down. At this time, the boss portions 27a and 27b of the support block 20 positioned on the lower side as described above are inserted into the boss hole portions 33a and 33b of the support column portions 21a and 21b on both ends of the support block 20 positioned on the upper side. Then, as shown in FIGS. 4A to 4D, in the column portion 21a, the claw portions 28a and 28b of the boss portion 27a are inserted into the locking holes 34a and 34b of the corresponding boss hole portion 33a. Then, it is easily locked by engaging with the claw receiving portions 35a and 35b. The column portion 21b is easily locked in the same manner as the column portion 21a.
　以上のように、簡易な構造の支持ブロック２０を用いて、ネジやナット等を用いることなく、所定高さの支持フレーム１３が形成される。また、下側に配置される支持ブロック２０の支持用切欠き部２３と、上側に配置される支持ブロック２０の受入用切欠き部２６とが上下に連通し、図１及び図２に示したように一つの孔のようになる。 As described above, the support frame 13 having a predetermined height is formed by using the support block 20 having a simple structure without using screws or nuts. Further, the support cutout portion 23 of the support block 20 disposed on the lower side and the reception cutout portion 26 of the support block 20 disposed on the upper side communicate with each other in the vertical direction, as shown in FIGS. 1 and 2. Like one hole.
　次いで、所定高さの支持フレーム１３を２つ対向配置し、２つの支持フレーム１３，１３間に棒状部材４０を支持させる。支持フレーム１３は、上下に積み上げられた支持ブロック２０，２０同士において、上記のように、支持用切欠き部２３と受入用切欠き部２６とが上下に連通している。そこで、まず、棒状部材４０の端部４１を、上側に配置される支持ブロック２０の受入用切欠き部２６に挿入する。この時、受入用切欠き部２６の正面から見た面積が、棒状部材４０の端部４１の断面積よりも大きいため、容易に挿入できる。そして、棒状部材４０の両端部４１，４１を、対向する受入用切欠き部２６，２６に挿入した後、そのまま押し下げ、各端部４１，４１のホゾ部４２，４２をそれぞれ支持用切欠き部２３，２３のアリ溝２４，２４に係合させる。これにより、ネジやナット等を用いなくても、棒状部材４０の端部４１は支持用切欠き部２３によって確実に支持される。棒状部材４０は、奥行き方向に好みの本数を配置すれば、所定幅の横フレーム１４が形成される。 Next, two support frames 13 having a predetermined height are arranged opposite to each other, and the rod-shaped member 40 is supported between the two support frames 13 and 13. In the support frame 13, the support notch portion 23 and the receiving notch portion 26 communicate with each other vertically in the support blocks 20, 20 stacked vertically. Therefore, first, the end portion 41 of the rod-like member 40 is inserted into the receiving cutout portion 26 of the support block 20 disposed on the upper side. At this time, since the area viewed from the front of the receiving notch 26 is larger than the cross-sectional area of the end 41 of the rod-shaped member 40, it can be easily inserted. And after inserting the both ends 41 and 41 of the rod-shaped member 40 into the notch parts 26 and 26 for reception which oppose, it pushes down as it is, and the relief part 42 and 42 of each edge part 41 and 41 is each a notch part for support. The dovetail grooves 24 and 24 of the 23 and 23 are engaged. Thus, the end 41 of the rod-like member 40 is reliably supported by the support cutout 23 without using screws, nuts, or the like. If the rod-shaped member 40 arrange | positions a favorite number in the depth direction, the horizontal frame 14 of predetermined width will be formed.
　以上のように、受入用切欠き部２６の正面から見た面積が、棒状部材４０の端部４１の断面積よりも大きいため、２つの支持フレーム１３，１３間に他の棒状部材４０が何本か既に配置された状態、すなわち、２つの支持フレーム１３，１３間の対向距離が確定している状態においても、棒状部材４０を任意の支持用切欠き部２３に挿入したり、あるいは、挿入済みのものを取り出したりすることが可能である。したがって、横フレーム１４を形成する棒状部材４０の配置、取り外しの自由度が極めて高く、使用者の好みの大きさ、形状の組立式ブロック構造１０が得られる。また、支持フレーム１３の高さも、支持ブロック２０の連結数により任意の高さにすることができる。 As described above, since the area viewed from the front of the receiving notch 26 is larger than the cross-sectional area of the end 41 of the rod-shaped member 40, what is the other rod-shaped member 40 between the two support frames 13, 13? Even in the state where the book is already arranged, that is, in the state where the facing distance between the two support frames 13 and 13 is fixed, the rod-like member 40 is inserted into any support notch 23 or inserted. It is possible to take out the used one. Therefore, the degree of freedom of arrangement and removal of the rod-like member 40 forming the horizontal frame 14 is extremely high, and the assembled block structure 10 having a size and shape desired by the user can be obtained. The height of the support frame 13 can also be set to an arbitrary height depending on the number of support blocks 20 connected.
　このため、例えば、図１に示したような低い高さの移動式ラック１１として使用したり、より高く設定して、図２に示したような本棚として使用したり、用途の自由度が極めて高い。その他、テレビ台、荷物棚、椅子、ベッドの架台部分等として使用することができる。また、部品の最小単位が支持ブロック２０または棒状部材４０であるため、これらを分解した際には極めてコンパクト化できるため、持ち運び、収納に便利である。 For this reason, for example, it can be used as a mobile rack 11 having a low height as shown in FIG. 1 or can be used as a bookshelf as shown in FIG. high. In addition, it can be used as a TV stand, luggage rack, chair, bed pedestal, etc. In addition, since the minimum unit of the parts is the support block 20 or the rod-like member 40, when they are disassembled, they can be made extremely compact, so that they are convenient to carry and store.
　また、支持ブロック２０として、長手方向の長さが異なるものを複数種類、準備したり、あるいは、棒状部材４０として長さの異なるものを複数種類準備したりしておくことが好ましい。例えば、図２に示したように、棒状部材４０の長さの異なるものを用いることで、組立式ブロック構造１０の幅（支持フレーム１３，１３間の間隔）を場所によって異ならせることができ、組立式ブロック構造１０の用途をさらに広げることができる。また、設置する部屋の大きさ等に合わせて種々アレンジすることができる。 Further, it is preferable to prepare a plurality of types of support blocks 20 having different lengths in the longitudinal direction, or to prepare a plurality of types of support members 20 having different lengths. For example, as shown in FIG. 2, the width of the assembly-type block structure 10 (interval between the support frames 13 and 13) can be made different depending on the location by using different rod-shaped members 40. Applications of the assembly block structure 10 can be further expanded. Also, various arrangements can be made according to the size of the room to be installed.
　次に、本発明の実施形態に係るロック解除具について説明する。
　ロック解除具６０は、図１及び図２の組立式ブロック構造１０における複数の支持ブロック２０，２０同士を連結したロック状態、あるいはキャスタ５０を支持ブロック２０に連結したロック状態を、アンロックするためのロック解除具６０である。 Next, the lock release tool which concerns on embodiment of this invention is demonstrated.
The unlocking tool 60 unlocks the locked state in which the plurality of support blocks 20 and 20 are connected to each other in the assembly block structure 10 in FIGS. 1 and 2 or the locked state in which the caster 50 is connected to the support block 20. The lock release tool 60 is.
　なお、前述の組立式ブロック構造１０は、前述の説明のように、複数の支持ブロック２０を上下に連結する際に、支持ブロック２０のボス部２７ａ，２７ｂを、上側に配置した支持ブロック２０のボス用穴部３３ａ，３３ｂに挿入する。前記ボス部２７ａ，２７ｂの周面に設けたそれぞれの爪部２８ａ，２８ｂがボス用穴部３３ａ，３３ｂのそれぞれのロック用孔部３４ａ，３４ｂの爪受部３５ａ，３５ｂに係合することによってロック状態となる。 As described above, when the plurality of support blocks 20 are connected up and down, the assembly block structure 10 described above has the boss portions 27a and 27b of the support block 20 arranged on the upper side. Insert into the boss holes 33a and 33b. By engaging the claw portions 28a and 28b provided on the peripheral surfaces of the boss portions 27a and 27b with the claw receiving portions 35a and 35b of the lock hole portions 34a and 34b of the boss hole portions 33a and 33b, respectively. It becomes locked.
　ロック解除具６０は、本実施形態では、図７および図１４に示すように、支持ブロック２０の幅方向の両側面から挟めるように、平面でＵ字形状に湾曲した保持部６１と、前記保持部６１の両先端部に互いに対向するように配置した突当て部６２ａ，６２ｂと、前記各突当て部６２ａ，６２ｂの先端面に形成した突当て用傾斜部６３ａ，６３ｂと、を備えている。 In this embodiment, as shown in FIGS. 7 and 14, the unlocking device 60 includes a holding portion 61 that is curved in a U shape in a plane so as to be sandwiched from both side surfaces of the support block 20 in the width direction, and the holding device 61. The abutting portions 62a and 62b are arranged so as to be opposed to the both end portions of the portion 61, and the abutting inclined portions 63a and 63b are formed on the end surfaces of the abutting portions 62a and 62b. .
　前記突当て部６２ａ，６２ｂは、例えば、支持ブロック２０の支柱部２１ａのロック用孔部３４ａ，３４ｂに挿入して爪部２８ａ，２８ｂの外面に備えた傾斜部３１ａ，３１ｂに突き当てるものである。突当て用傾斜部６３ａ，６３ｂは、突き当てる爪部２８ａ，２８ｂの傾斜部３１ａ，３１ｂと逆方向に傾斜するように形成したものである。なお、「逆方向に傾斜」とは、爪部２８ａ，２８ｂの傾斜部３１ａ，３１ｂが上から下に向かって突出する裾広がりに傾斜するのに対し、突き当て用傾斜部６３ａ，６３ｂが、上部が最も内方に突出し、下方に向かって徐々に外方に向かう傾斜面になっているという意味である。したがって、図８（ａ）に示したように、爪部２８ａ，２８ｂの傾斜部３１ａ，３１ｂと突き当て用傾斜部６３ａ，６３ｂ同士は、突き当てた状態では面接触することになる。 The abutting portions 62a and 62b are inserted into the locking hole portions 34a and 34b of the support column portion 21a of the support block 20, for example, and abut against the inclined portions 31a and 31b provided on the outer surfaces of the claw portions 28a and 28b. is there. The abutting inclined portions 63a and 63b are formed so as to be inclined in the opposite direction to the inclined portions 31a and 31b of the claw portions 28a and 28b to be abutted. Note that “inclined in the reverse direction” means that the inclined portions 31a and 31b of the claw portions 28a and 28b are inclined so as to project from the top to the bottom, whereas the abutting inclined portions 63a and 63b are It means that the upper part protrudes most inward and has an inclined surface that gradually goes outwards downward. Therefore, as shown in FIG. 8A, the inclined portions 31a and 31b of the claw portions 28a and 28b and the abutting inclined portions 63a and 63b are in surface contact with each other in the abutted state.
　ロック解除具６０は、図８（ａ）に示すように、例えば、ロック状態の支持ブロック２０の支柱部２１ａの幅方向の両側面から挟むようにして、突当て部６２ａ，６２ｂをロック用孔部３４ａ，３４ｂに挿入する。突当て部６２ａ，６２ｂの先端面の突当て用傾斜部６３ａ，６３ｂを、爪部２８ａ，２８ｂの外面の傾斜部３１ａ，３１ｂに突き当てる。 As shown in FIG. 8A, for example, the unlocking tool 60 sandwiches the abutting portions 62a and 62b from the both side surfaces in the width direction of the support column portion 21a of the support block 20 in the locked state. , 34b. The abutting inclined portions 63a and 63b on the front end surfaces of the abutting portions 62a and 62b are abutted against the inclined portions 31a and 31b on the outer surfaces of the claw portions 28a and 28b.
　次に、突当て部６２ａ，６２ｂを押圧すると、図８（ｂ）に示すように、突当て部６２ａ，６２ｂが、ボス部２７ａの爪部２８ａ，２８ｂの傾斜部３１ａ，３１ｂを爪部用バネ片２９ａ，２９ｂの付勢力に抗して内側へ押圧する。すると、図８（ｃ）に示すように、突当て部６２ａ，６２ｂの突当て用傾斜部６３ａ，６３ｂが、爪部２８ａ，２８ｂの傾斜部３１ａ，３１ｂを滑って相対的に上方へ移動するので、突当て部６２ａ，６２ｂがロック用孔部３４ａ，３４ｂを相対的に上方へ移動させる。その結果、爪部２８ａ，２８ｂがロック用孔部３４ａ，３４ｂの爪受部３５ａ，３５ｂから外れて簡単にアンロックすることができる。 Next, when the abutting portions 62a and 62b are pressed, the abutting portions 62a and 62b use the inclined portions 31a and 31b of the claw portions 28a and 28b of the boss portion 27a as shown in FIG. 8B. The spring pieces 29a and 29b are pressed inward against the urging force of the spring pieces 29a and 29b. Then, as shown in FIG. 8C, the abutting inclined portions 63a and 63b of the abutting portions 62a and 62b slide relatively on the inclined portions 31a and 31b of the claw portions 28a and 28b. Therefore, the abutting portions 62a and 62b move the locking holes 34a and 34b relatively upward. As a result, the claw portions 28a and 28b can be easily unlocked by being detached from the claw receiving portions 35a and 35b of the locking holes 34a and 34b.
　組立式ブロック構造１０は、例えば、図９に示すように、組立式棚１２の背面側に筋かい７０を設けることによって安定する。そこで、支持ブロック２０は、図３及び図１０（ａ）に示すように、長手方向に対して直交する側面に、複数の筋かい固定用穴３８を横方向に配置することが望ましい。上記の複数の筋かい固定用穴３８は、上下方向に適宜間隔を介して配置することができる。本実施形態では、３個の筋かい固定用穴３８，３８，３８を設けている。 The assembly block structure 10 is stabilized by providing a brace 70 on the back side of the assembly shelf 12 as shown in FIG.
